I was answering your question. There are certain things that can effect the eyes, like jaundice, or a direct blow to the pupil, or macular degeneration from old age. The study of this phenomena is known as optometry, and that includes the iris. Iridology is bullshit science though. How the hell would the iris know the difference between getting fucked voluntarily and getting raped? How in the hell would that cause coloboma?
